, "This invention relates toa 'ma chineior use in assembling hose coupling parts and the like, and an objectof the invention is to provide a machine which is simple, practical and eflicient and which includes partsadapted for quickly and easily squeezing inwardly simultaneously from' all radial directions an b p to be'taken as a part of this specification, and

annular sleeveportion of a 'coiupling'or, the

' chine by which to reduce by compression diameter'to engage withinan annular groove like to thereby assemble the coupling parts.

A' more specific objectis to provide a mafrom all radial directions the diameter of an annular sleeve portion of one member ofaa two-part coupling so that an annular; rib of said member. which isnormally of such-diameter to permit easy assembly of the' two'cou? pling parts willbecondensed and reduced in of the secondcoupling member .in a manner to provide swivel connection between [the I coupling; members;

A j'further specific object is to provide a machine so constructed asto comprise means for rece ving support ng the .two coupling. members in registering relation to each Y other, a multlpllcity of pressermembers pos1.-

reference characterL indicates one of the rel-ratively movable. members, of the pmachine while the reference characterGindic ates'the other relatively movable memberofthe'machine. While itwill be seen thatit is im material which of; these members actual-1y moves"andwhichis stationary, the member tionary member and the member G a movable member; The member L is provided with a carrying bracket or base'l by; which itqmay I bejsattache dflto any suitable support or plat forni 2;

The member G is arranged parallel with the front face as 3 of member L and carries a pair ofguide rods-as 4 and 5 which are mounted slidably within bearing openings as 6 and 7 provided through the member L so that the member G is movable toward and away from the member L but is always held in proper alignment during such movement.

At their rear ends the rods 4 and 5 carry a connecting plate 8 upon the forward face of which is supported a'plunger 9 slidably engaging within a cylinder 10 formed to receive it upon the rear side of the member L. The plunger may be fitted with any form of gasket or other sealing device as 11, and a source of compressed air maybe fed into the cylinder by means of a pipe 12 in which '-is arranged a manually operable valve 13 by which air under pressure may be introduced ;into the cylinder at will for forcing the plunger outwardly and hence for forcing thememher Gtoward the member L. y T V One or more springs as 1414 may be arranged at convenient points between the members L and G for normally urging them apart, and an outlet as 15 may be provided upon the valve.13 whereby the air pressure within thecylinder may be relieved to the atmosphere.

.It will be understood that while the fluid controlled mechanism just described. for-producingrelative movement of the members L andG is considered desirable for the purpose, nevertheless any other mechanism may be employed forthis purpose if preferred.

Centrally of its'forward face'the member .L is hollowed out to provide a recess 16 for receiving the presser members 1717. Centrally of the recess is arranged a cylindrical stud 18 about which the presser members are arranged equi-distant as clearly indicated in Fig. 4. The stud 18 may be formed as an integral part of the member L if desired but itis preferably formed separately from said member and connected thereto by means of a clamp bolt 19 extending longitudinally therethrough and engaging within a threaded aperture in the base of-the'recess 16 whereby it in turn is adapted to serve as aclamp member for a wear'orthrustplate 20 lying against the base of the recess having a central opening 21 through which the screw 19 and a surrounding portion of stud 18 projects. An

annular shoulder 22 of thestud overlies the forward face of the thrust plate to hold it firmly'in position. j

The presser members 17-17 are all of "identical shape and size. Each consists of an elongated steel body arranged'longitudinally of the stud 18 having one endproject ing rearwardly into the recess'16 and the other end projecting forwardly out of said The rear end as 23 is rounded and is received within a correspondingly rounded in the thrust plate 20. The forward end projects beyond the end of the stud 18 and is shaped to provide a nose portion 25 projecting inwardly at its inner face and a cam surface 26 on its outer face.

The nose 25 is intended to directly engage against the work-that is, in the instance illustrated, against the outer edge of the outflaring annular sleeve portion as 27 of the coupling member 28 for squeezing this sleeve portion into true cylindrical form with the internal rib as 29 on said portion engaging within the annular groove 30 which is provided to receive it upon the mating coupling member 31, and the cam 26 is intended to be engaged by a cam 32 which is carried by the member G for forcing the nose against the.work as the member Gr moves toward the member L.

Any appropriate means may be provided for retaining the presser members assembled with their rear ends engaging within the seats 24 but for this purpose the drawing illustrates a retaining ring 33 fixed to the forward face of member L as by means of clamp screws 34. This ring has a series of notches as 3535 provided in its inner annular edge one for receiving each of the presser members, and each of the presser members is formed with a forwardly facing arcuate tween them the drawing illustrates a. series of small coil springs as 38 38 one for each -presser member, being arranged in pockets as 8 9 of the stud 18 and exerting a constant pressure againstthe inwardly facing surface of the respective presser member. The outer end walls as 40 of the notches 35 serve as stops to limit the outward movement of the presser members under pressure from these spr ngs,

" The :cam 32 on member G is in the form of an annular ring inconcentric alignment with the stud 18 at all times. It is carried rigidly upon the member to move therewith toward and away from the member L and its surface which engages the cam portions 26 of the presser-members is annular so that it has simultaneous camming action against all of the presser members asthe member G moves. Preferably this surface is formed relatively steep at one part as at 41 and relatively fshallow at another part as at 42. The steep part 41 is arranged to engage the presser members when the member G is relatively far from themember L, while the shallow part 42 is intended to engage V the other coupling member.

m It is particularly" noted that openingas 45 through thecam 32 affords v ample and convenient access to the .presser members for inserting and removing the couthe presser members as the member moves closer to the member L. V The purpose of this arrangement is to. enable a wide spread of h the presser'members collectively with relatively shortmovement of the member Grand a corresponding rapid return movement ofv the presser members into engagement with the work, while the part 42 is designed to impart a more gradualand a more. powerful pressure against the presser members] after the press er members have come into engagement with the"tworli, as Wlll. be readily understood from an 'inspectionof' the drawings. I V

It will be seen from this disclosure that the 'mechanislnis, simple and" compact, that it provides highly efiicientmeans for contracting and condensing the material of the sleeve portion 27 of the coupling member 28 for at once strengthening said portion and causing it to permanently interengage' with The presser members 17 constitute collectively what maybe conveniently termed a coupling assembling'means;surrounding the stud 18 andmovable withrespect' thereto for j performing their function of assembling the coupling parts. 7 p v Inoperation it is simply necessary'to introduce a coupling member 28 intoposition between the presser members, being conveniently supported in said position by beingre ceived in an annular seat as 43 provided for the purpose at the forward end of the stud 18. After the member'28 has been thus positioned the mating coupling member is introduced,.being conveniently located by Contact against the forward end surface as 44 of the stud. 18. Then the air pressure is admitted 1 ,to cylinder for moving the member'G and thereby squeezing the presser members together and forcing the rib 29 of the member 28 into the groove 30.
